| 英文摘要 | Microfracturing processes of sandstone and Oshima granites soaked in air, water, chemical solutions DTAB and PEG, have nonlinear evolution properties. Their temporal fractal properties vary as soaking environments. At most of cases it seems to be possible to define two or three fractal subranges (multi fractal structure). Whatever variations are present in fractal properties (from a single fractal structure to multi-fractal structure with D-1 > D-2 or D-1 < D-2), the lower fractal dimension is generally produced near the failure. The results of predictions for new cases indicate the neural network NN(n, h, m) can be used to describe well acoustic emission event and count evolution in mcirofracturing process of rocks soaked in air. water, chemical solution DTAN and PEG. The number n and h, which vary as conditions of stress environmental erosion, can be adaptive determined by using proposed evolutionary learning algorithm. |
